Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed NOVemher 3, 1904. Serial N0. 231,319.

To rtl/ 7071/0721/ if may concern,.-

Be it known that I, CHARLES FELLNER, a subject of the Emperor of Austria-Hungary, residing at VIII Barossutera 79 N., Budapest, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Boiler-Cleaning Devices, of' which the f'ollowing is a specification.

My invention relates to boiler-cleaning devices; and it consists of' certain novel parts and combinations of' parts, particularly pointed out in the claims concluding this specification.

In steam-boilers in which steam is rapidly generated i f` the water be not purified before it enters the boiler a sediment of' `slime or in the case of hard water of lime is formed which attaches itself' to the boiler-surfaces, resulting in permanent injury by burning or blistering of` the surfaces exposed to the action of the flames unless energetic means are employed to remove the sediment.

In the accompanying drawings I have shown my invention applied in forms which are at present preferred by me; but it will be understood that various modifications and changes may be made without departing' from the spirit of my invention and without exceeding' the scope of` my claims.

Figure 1 represents a vertical section through walls of' the water-space of a boiler, showing' the nozzle or mouthpiece for conveying a cleansing' fluid, such, for example, as steam or water. Fig. 2 is a horizontal section through the walls of the water-space and the nozzle or mouthpiece shown in Fig. l. Fig. 3 shows a modified form ofl nozzle or mouthpiece involving my invention. Fig. A is a horizontal section through a boiler, showing in place the entrance and discharge nozzles for conveying' the cleaning fluid into and from the water-space.

Similar figures of reference indicate the same or corresponding parts in all the fig'ures.

Referring' to Fig. LI, l l and 2 2 are the water-spaces of a steam-generator, which spaces are substantially annular in form. 5 is a funnel-shaped nozzle, and 7 is a supply-pipe therefor controlled by a cock 3. 6 is a similar nozzle or mouthpiece turned in the opposite direction connected with the pipe 7, which is controlled by a cock 4. Cleansing fluid (such as steam or water) is introduced under pressure through the nozzle 5 and after circulating around the water-space is discharged through the nozzle 6. Such nozzles may be placed at the points where the sediment collects-for example, in a vertical boiler near the bottom thereof-and the cleansing fluid when admitted violently agitates the Water contained in the space and dislodges and carries off the sediment which it contains.

In Figs. l and 2 I have shown the funnelshaped mouthpiece or nozzle 5 and 6 in detail in the form of a hood bolted to the Wall of the water-space, while in Fig. 3 I have shown it in the form of' a tube passing through the Wall of` the water-space and expanded at the end in funnel shape. Such nozzles can be placed at various points in the boiler, and the direction in which the nozzle or mouthpiece points can be varied or adjusted to direct the cleansingstream in any desired direction.,

The nozzles above described afford means for cleaning the boiler without interrupting its operation by connecting the entrance-pipe with the feed-water pump and Working said pump rapidly while the exit-pipe is open to permit the sediment to be blown out.

Itwill be observed that owing to the annular form of' the water-space 2 and the expanded f'orm of the inlet and outlet nozzles substantially the entire body of water contained in said water-space is by the action of the apparatus put into rapid motion and speedily expelled from the boiler, so as to effect the cleaning in a very short space of time.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination with a steam-boiler, of' entrance-nozzle and discharge-passage located in substantially the same horizontal plane in the water-space ofl the boiler in such relation as to afford means for causing a rapid circulation of cleaning fluid therethrough.

2. The combination with a steam boiler having an annularl water-space, of entrancenozzle and discharge-passage located in said space in such relation as to afford means f'or causing a rapid circulation of cleaning fluid therethrough.

3. The combination with a steam-boiler, of entrance-nozzle having an expanding section IOO and discharge-passage having' a contracting' section and being located in the Water-space of the boiler in such relation as to alford means for causing' a rapid circulation of cleansing fluid therethrough.

A. The combination with a steam-boiler having an annular Water-space, an entrance-noz- Zle having an expanding' section and a discharge-passage having a contracting section located in the Water-space of the boiler in such relation as to afford means for causing a rapid circulation of cleansing fluid therethrough.

5. The combination with a steam-boiler having an annular Water-space, oi' an entrancenoZZlc and a discharge-passage located in substantially the same horizontal plane in the Water-space of the boiler in such relation as vto this specification in the presence of two subscribing Witnesses.
